摘要
在三维编织复合材料的实体单胞模型的基础上 ,考虑了编织结构和编织纱线的几何特性 ,采用局部 /整体均匀化的方法 ,计算了三维编织复合材料的宏观性能 .利用 MARC有限元分析软件的用户接口 ,分析了三维编织复合材料工字梁的弯曲性能 .计算结果与实验结果吻合较好 .
Based on the solid unit cell model,the elastic properties of three dimension braided composites are calculated using the local/global uniform method according the braided structure and the geometrical characteristics of yarns.As an example,the bending properties of an I shaped beam is analyzed through the user interface of the finite element software MARC.Good agreement between the numerical results and the experimental data has been obtained.
